INSTALLATION DIAGRAMS

DIAGRAM NOTES

VX.002 - The power unit can power

up to 10 distributors. Use one

local power unit Ref. 789/2 for

each group of distributors (max.

20) after exceeding this limit.

VX.003 - MINIMUM WIRE

CROSS-SECTION AREAS

Provide two wires for switching on

the push-button panel light bulbs.

Use a separate transformer suitable

to the number of light bulbs.

(Transformer ref. 9000/230 is

recommended for up to 5 bulbs).

The system power unit is sufficient

for up to 2 bulbs.

VX.006 - See the instruction book

provided with the product for fitting

the accessory in the device.

VX.007 - The cross-section area of the

wires indicated with must be

double.

VX.010 - No more than 20 monitors

should be connected to each column;

add video distributors to the

camera output or other device if

there are more devices.

VX.014 - Dusk switch or similar device

for switching lights on, where

relevant.

VX.012 - Relay Ref.788/5 or Ref.788/52

is needed to prevent that a video door

phone can be switched on while another

device is working and interrupt vision.

Connect the PS wire directly to the

monitor X1 terminals if the relay is

not fitted.

VX.011 - Close the coaxial wire on

the last monitor in the riser with

a 75 Ohm resistance between

terminals V4 and V5.

VX.013 - Connect the switch-off

circuit Ref. 5330/60 in the

push-button panel and connect wire SN

(brown) to the button common. Cut and

isolate wire 1 (red).

Utility

VX.015 - The power unit Ref.1090/850

can power up to 4 devices.

Use another power unit for each group

of 4 devices if the system exceed

this capacity.

Voice and

call wires

Use a normal coaxial wire

for distances up to 300 m

Add a video amplifier for

longer distances.

The video amplifier must be installed

near the monitor.

Two BNC connectors are required for

connecting the coax wire. Use a RG59

(75Ohm) coax for a maximum distance

of 300m.

Use video amplifier Ref.1840/250 with

RG11 wire for higher distances
